Wheel bearing
Encyclopedia
The term wheel bearing may refer to any one of the following:
- A Ball bearingBall bearingA ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit...
- A Bearing (mechanical)Bearing (mechanical)A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can...
- A Fluid bearingFluid bearingFluid bearings are bearings which support the bearing's loads solely on a thin layer of liquid or gas.They can be broadly classified as fluid dynamic bearings or hydrostatic bearings. Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and...
- A Jewel bearingJewel bearingA jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter. The jewel material is usually synthetic sapphire...
- A Journal bearing
- A Needle roller bearingNeedle roller bearingA needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surface.Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings...
- A plain bearingPlain bearingA plain bearing, also known as a plane bearing or a friction bearing is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore the journal slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole...
- Any Rolling-element bearingRolling-element bearingA rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing round elements between the two pieces...
- A Self-aligning ball bearing
- A Spherical roller bearingSpherical bearingA spherical bearing is a bearing that permits angular rotation about a central point in two orthogonal directions...
- A Tapered roller bearingTapered roller bearingTapered roller bearings are bearings that can take large axial forces as well as being able to sustain large radial forces.-Description:...
- A Thrust bearingThrust bearingA thrust bearing is a particular type of rotary bearing. Like other bearings they permit rotation between parts, but they are designed to support a high axial load while doing this.Thrust bearings come in several varieties....
